Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nasogastric tubes, in particular to a rigid nasointestinal tube which is convenient to connect with a syringe. Background Technique
[0002] The nasogastric tube is mainly composed of a polyurethane catheter and a stainless steel guide wire. Clinically, this product is suitable for the infusion of enteral nutritional solutions to patients through nasogastric feeding.
[0003] For the existing nasogastric tube, since a side tube needs to be connected for injecting contrast agent, it is necessary to connect through a medical connector in the middle of the pipeline. However, when feeding, when the syringe forces the liquid food into the nasogastric tube, the medical connector is likely to fall off, causing the liquid food to overflow and affecting the normal progress of feeding. Content of the Utility Model
[0004] The utility model provides a rigid nasointestinal tube which is convenient to connect with a syringe, and solves the above technical problems.
[0005] To solve the above technical problems, a rigid nasointestinal tube which is convenient to connect with a syringe provided by the utility model includes a feeding tube. A feeding esophageal tube is fixed at the lower end of the feeding tube. A three-way joint is connected to the lower end of the feeding esophageal tube. A connecting tube is connected to one side of the three-way joint. A feeding tube is connected to the lower end of the three-way joint. A food outlet is arranged on the surface of the feeding tube.
[0006] Preferably, a plugging head is rotationally connected to the upper end of the connecting tube through a thread.
[0007] Preferably, the three-way joint includes a control box. A rotating block is rotationally connected inside the control box. An adjusting block is fixed to the upper end of the rotating block.
[0008] Preferably, a positioning tube is fixed to the surface of the control box. An inner tube is fixed to the inner surface of the positioning tube.
[0009] Preferably, an outer tube is fixed to one end of the positioning tube. An extrusion ring is rotationally connected to the outer surface of the positioning tube through a thread.
[0010] Compared with the related technology, a rigid nasointestinal tube which is convenient to connect with a syringe provided by the utility model has the following
[0011] Advantageous effects:
[0012] By extruding the outer tube with the extrusion ring, the pipeline is extruded onto the surface of the inner tube. When the syringe injects with a large pressure, the pipeline can be prevented from falling off, ensuring the normal progress of feeding. Description of the Drawings

Specific implementation manner
[0017] The embodiment is given by Figures 1-3 The present utility model includes a rigid nasointestinal tube that is convenient for connecting a syringe, including a feeding pipe 7. A feeding tube 1 is fixed to the lower end of the feeding pipe 7. A tee joint 4 is connected to the lower end of the feeding tube 1. A connecting tube 3 is connected to one side of the tee joint 4. A feeding tube 5 is connected to the lower end of the tee joint 4. A food outlet 6 is arranged on the surface of the feeding tube 5.
[0018] The upper end of the connecting tube 3 is rotationally connected with a plugging head 2 through a thread.
[0019] The tee joint 4 includes a control box 46. A rotating block 45 is rotationally connected to the inside of the control box 46. An adjusting block 41 is fixed to the upper end of the rotating block 45.
[0020] A positioning tube 47 is fixed to the surface of the control box 46. An inner tube 42 is fixed to the inner surface of the positioning tube 47.
[0021] One end of the positioning tube 47 is fixed with an outer tube 43. An extrusion ring 44 is rotationally connected to the outer surface of the positioning tube 47 through a thread.
[0022] Insert the syringe into the feeding pipe 7, push the syringe to push the liquid food inside into the feeding tube 1. The liquid food flows out from the food outlet 6 through the feeding tube 5. The feeding tube 1, the connecting tube 3, and the feeding tube 5 are sleeved on the surface of the inner tube 42. The outer tube 43 is arranged outside the feeding tube 1, the connecting tube 3, and the feeding tube 5. The extrusion ring 44 moves on the surface of the positioning tube 47 through the thread on the surface, and extrudes the outer tube 43 to ensure the stable connection of the feeding tube 1, the connecting tube 3, and the feeding tube 5.
